I have my ASP.NET Core app running beautifully (more or less) on microsoft/aspnetcore:2.0-jessie. Now I want to try to get it to deploy to amazonlinux:2.
So far, the biggest hurdle has been libicu. I tried setting Globalization to Invariant, but this caused weird failures in, e.g., mySQL database calls.
Here's the relevant step from my Dockerfile:
RUN curl -L --http1.1 http://download.icu-project.org/files/icu4c/57.1/icu4c-57_1-RHEL6-x64.tgz --output icu.tgz \
&& tar -xf icu.tgz -C / \
&& export LD_LIBRARY_PATH=/usr/local/lib \
&& rm icu.tgz
(SourceForge was down while I was trying to work on this yesterday, which didn't improve matters.)
In any case, I still get the message of doom from .NET Core:
FailFast: Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.
Any suggestions how to proceed?
Well, I revisited this yesterday. I don't know if it's because the base .tar of the Amazon Linux image has been updated, or because I was doing something wrong last time, but I installed the following packages using yum and all was well:
Note that for the dotnet package I needed first to set up Microsoft's package repository for yum, i.e.
rpm --import https://packages.microsoft.com/keys/microsoft.asc
and copying the following file to /etc/yum.repos.d/dotnetdev.repo :
[packages-microsoft-com-prod]
name=packages-microsoft-com-prod
baseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod
enabled=1
gpgcheck=1
gpgkey=https://packages.microsoft.com/keys/microsoft.asc
(see Microsoft's instructions for CentOS and other Linux distros)
